Description

  The present invention relates to a recording system for recording imaging data and a wearable camera having portability that can be worn on the body.

In recent years, the introduction of wearable cameras has been considered to support the operations of police officers and guards.
Conventionally, an authentication system using a wearable camera has been developed. For example, there is one described in Patent Document 1. The authentication system described in Patent Document 1 includes a portable terminal that is a flashlight with a camera, a cradle having a charging function for the portable terminal, and a personal computer connected to the cradle, and the system is used for security. When a security patrol is to be started, a security guard (user) who wants to start a patrol patrol first performs an authentication operation including input of personal authentication information, and then removes the mobile terminal from the cradle. In response to this extraction, recording is started at the portable terminal, and a security start notification mail including authentication result data is transmitted from the personal computer to the external device connected to the personal computer. When the security guard finishes patrol and returns the mobile terminal to the cradle, a security end notification mail is transmitted to the external device. Thereafter, the recording on the portable terminal is terminated, and the image data is transferred to the main recording medium in the personal computer.

For example, when authenticating, the CPU 31 authenticates whether or not the user can log in to the in-vehicle camera system 2 by a user input operation on a login screen (not shown) to the in-vehicle camera system 2 displayed on the display unit 36 (user Authentication). The user input operation is, for example, an operation of inputting an ID (user identification information), a password, and the like.

  Various types of information related to a user who is permitted to log in are stored in advance in, for example, the memory 34, and the CPU 31 uses the information on the target of permitted login stored in the memory 34 in advance, so 2 authenticates (determines) whether or not login to 2 is possible. The login may be a login to the in-vehicle camera system 2 via the PC 3, or a login to an application for operating the in-vehicle camera system 2 mounted on the PC 3.

  The I / O control unit 32 controls the input / output of data between the CPU 31 and each unit of the PC 3 (specifically, the communication unit 33, the input unit 35, the display unit 36, the speaker unit 37, and the storage unit 38).

  FIG. 4 is a block diagram illustrating a schematic configuration of the wearable camera 1. In the figure, the wearable camera 1 includes a recording button 12, a snapshot button 13, a W-LAN button 14, LEDs 15 to 17, a contact terminal 18, an imaging unit 100, a GPIO (General Purpose Input / Output) 101, a RAM 102, a ROM 103, SD memory 104, EEPROM (Electrically Erasable Programmable Read-Only Memory) 105, RTC (Real-Time Clock) 106, GPS (Global Positioning System) 107, CPU (Central Processing Unit) 108, Communication unit 109, USB (Universal Serial Bus) ) 110, a power supply unit 111, and a battery 112. Note that the SD memory 104 is a medium that is detachable from the wearable camera 1 and is specifically an SD card or the like, but may be built in the wearable camera 1 main body.

  The CPU 108 functions as the separation detection unit 130 using the communication unit 109. The CPU 108 also functions as a recording start control unit.

  The imaging unit 100 includes a solid-state imaging device such as a CCD (Charge Coupled Device) type image sensor or a CMOS (Complementary Metal Oxide Semiconductor) type image sensor, and outputs imaging data. The imaging unit 100 is provided with the lens 100A described above. The GPIO 101 is a parallel interface, and inputs and outputs signals between the recording button 12, the snapshot button 13, the W-LAN button 14 and the LEDs 15 to 17 and the CPU 108.

  The RAM 102 is a work memory used in the operation of the CPU 108. The ROM 103 stores a program for controlling the CPU 108. The SD memory 104 stores imaging data obtained from the imaging unit 100. The SD memory 104 can be attached / detached to / from the main body of the wearable camera 1. The EEPROM 105 stores the serial number of the wearable camera 1. The RTC 106 outputs current time information. The RTC 106 has a dedicated battery (not shown), and has a function of keeping the current time even when the wearable camera 1 is turned off. The CPU 108 functions as a recording timer 132 using the RTC 106.

  The GPS 107 receives radio waves transmitted from an artificial satellite arranged in the earth orbit, measures latitude, longitude, altitude, and time, and outputs the result as position information and time correction information. The communication unit 109 performs wireless communication with the video recorder 21 of the in-vehicle camera system 2 using, for example, a W-LAN system of the IEEE 802.11 standard. The USB 110 is a serial bus, and enables a wired connection between the wearable camera 1 and the video recorder 21 of the in-vehicle camera system 2. The power supply unit 111 charges the battery 112 with power supplied via the contact terminal 18. The battery 112 supplies power for operating each part of the wearable camera 1.

  The CPU 108 operates according to a program stored in the ROM 103. The CPU 108 uses the RAM 102 in its operation, obtains current time information from the RTC 106, and obtains position information and time correction information from the GPS 107. In addition, the CPU 108 detects pressing of each of the recording button 12, the snapshot button 13, and the W-LAN button 14, and performs processing for the button with the operation. That is, when the recording button 12 is pressed, moving image shooting is performed by the imaging unit 100, and imaging data obtained from the imaging unit 100 is stored in the SD memory 104 as a moving image. Further, when the recording button 12 is pressed, the LED 16 is turned on. When the snapshot button 13 is pressed, the image capturing unit 100 performs still image capturing, and the captured image data is stored in the SD memory 104 as a still image.

  When the W-LAN button 14 is pressed, W-LAN communication is performed with the video recorder 21 of the in-vehicle camera system 2 using the communication unit 109. When the W-LAN button 14 is pressed, the LED 17 is turned on. At this time, if the communication mode is the access point mode, the first color is lit, and if the station mode is the station mode, the second color is lit.

  When the CPU 108 detects that the W-LAN button 14 is pressed, the CPU 108 starts wireless communication with the video recorder 21 of the in-vehicle camera system 2, and after the link is established, the wearable camera 1 and the in-vehicle camera system 2 Monitor the distance between. When the CPU 108 detects that the distance between the wearable camera 1 and the in-vehicle camera system 2 is more than a predetermined distance (for example, 5 m), it starts recording. That is, moving image capturing is started by the image capturing unit 100, and image data obtained from the image capturing unit 100 is stored in the SD memory 104 as a moving image.

  Further, the CPU 108 lights the LED 16 at the start of recording, sets a timer value in the recording timer 132, and sets the remaining recording time. The recording timer 132 prevents storage capacity compression due to forgetting to stop recording and power consumption of the built-in battery. The timer value and the remaining recording time of the recording timer 132 may be set as fixed values in the wearable camera 1 itself (for example, stored in the ROM 103), or a button for setting the wearable camera 1 is provided. The wearable camera 1 may allow the user to set an arbitrary value.

  The timer value of the recording timer 132 is, for example, 10 minutes, and the remaining recording time is, for example, 30 seconds. In this embodiment, these values are used.

  When the remaining recording time reaches 30 seconds from the start of recording, the CPU 108 changes the LED 16 from a lighting state to a blinking state. Then, when it is detected that the recording button 12 is pressed by the user before the remaining recording time elapses, the timer value of the recording timer 132 is reset. That is, it is set to 10 minutes. Further, when the timer value is reset, the LED 16 is changed from the blinking state to the lighting state. If the recording button 12 is not pressed until the remaining recording time elapses, the CPU 108 stops recording, turns off the LED 16, and clears the timer value of the recording timer 132. It should be noted that by pressing the record button 12 twice in succession at short intervals (that is, by double-clicking the record button 12), the resetting of the timer value is enabled to prevent erroneous operation. be able to.

  In the case of timer recording, a recording leak may occur if the remaining recording time is not always taken care of. However, the present invention notifies the user by blinking the LED 16 when the remaining recording time reaches a preset value, and the timer value. Since it is possible to extend the recording by resetting, it is possible to prevent the recording from being lost.

  In order to forcibly stop recording, the recording button 12 may be pressed for a long time (for example, 3 seconds). When the CPU 108 detects that the recording button 12 has been pressed for a long time, the CPU 108 stops recording. Note that the recording may be stopped when the distance between the wearable camera 1 and the in-vehicle camera system 2 is less than a predetermined distance.

  Here, as a method of determining whether or not the wearable camera 1 is away from the in-vehicle camera system 2 by a predetermined distance or more, a method for monitoring a communication state with the in-vehicle camera system 2, the positions of the wearable camera 1 and the in-vehicle camera system 2 are determined. There is a way to monitor. The former method of monitoring the communication state with the in-vehicle camera system 2 includes a method for determining whether communication with the in-vehicle camera system 2 has been interrupted, and the radio wave when the radio wave transmitted from the in-vehicle camera system 2 is received. There are methods for determining the magnitude of the electric field strength.

  Whether communication with the in-vehicle camera system 2 has been interrupted can be determined by the output of the communication unit 109. The electric field strength of the radio wave when the radio wave transmitted from the in-vehicle camera system 2 is received is, for example, a function for detecting a high-frequency received signal obtained when receiving the radio wave, converting it to digital, and outputting it to the communication unit 109. In addition, it can be determined by the output of the function. The positions of the wearable camera 1 and the in-vehicle camera system 2 can be determined from position information obtained from the GPS 107. In the present embodiment, based on the fact that communication with the in-vehicle camera system 2 has been interrupted, the separation between the wearable camera 1 and the in-vehicle camera system 2 is determined beyond a predetermined distance.

Note that, when the separation distance between the wearable camera 1 and the in-vehicle camera system 2 is determined based on the position information obtained from the GPS 107, the CPU 108 and the GPS 107 constitute the separation detection unit 131.
As triggers for automatically starting recording, the following methods can be considered as those that can be used in combination with distance detection.
-A method of detecting the difference between the direction of the police car 520 and the police officer with the built-in compass and using the result.
A method in which an atmospheric pressure sensor is added to the wearable camera 1, and a change in the atmospheric pressure in the vehicle when the door of the police car 520 is opened is detected by the atmospheric pressure sensor, and the result is used.
A method of detecting the movement speed of the police officer (difference from the police car 520) with the GPS 107 and using the result.

  FIG. 5 is a flowchart for explaining the operation of the wearable camera 1. In the figure, the CPU 108 of the wearable camera 1 detects that the wearable camera 1 is separated from the in-vehicle camera system 2 by a predetermined distance or more while a link is established with the video recorder 21 of the in-vehicle camera system 2. If so, recording starts (step S1). At this time, the CPU 108 turns on the LED (recording LED) 16, sets the timer value X (minutes) in the recording timer 132, and sets the remaining recording time Y (seconds). In this case, it is assumed that the timer value is set to 10 minutes and the remaining recording time is set to 30 seconds.

  The CPU 108 determines whether X (minutes) -Y (seconds) has elapsed after starting the recording (step S2). That is, it is determined whether 9 minutes and 30 seconds have elapsed. When it is determined that 9 minutes and 30 seconds have not elapsed (when “No” is determined in step S2), this determination is repeated until 9 minutes and 30 seconds have elapsed. On the other hand, when it is determined that 9 minutes and 30 seconds have elapsed (when it is determined “Yes” in step S2), the LED (recording LED) 16 is blinked (step S3). After blinking the LED 16, it is determined whether or not the recording button 12 has been pressed (step S 4). If it is determined that the recording button 12 has been pressed (when “Yes” is determined in step S 4), the recording timer 132 is restarted. Set (step S5), the process returns to the determination of step S2. On the other hand, when it is determined that the recording button 12 has not been pressed (when “No” is determined in step S4), it is determined whether 10 minutes have passed (step S6). In this determination, when it is determined that 10 minutes have not elapsed (when “No” is determined in step S6), the process returns to the determination in step S4. On the other hand, when it is determined that 10 minutes have elapsed (when “Yes” is determined in step S6), the recording is stopped, the LED (recording LED) 16 is turned off, and the timer value of the recording timer 132 is cleared. (Step S7). Then, this process is finished.

  As described above, according to the wearable camera 1 according to the present embodiment, when a predetermined distance or more away from the linked vehicle-mounted camera system 2, recording is started, the LED (recording LED) 16 is turned on, and the recording timer is turned on. The timer value X (minute) is set to 132, and the remaining recording time Y (second) is set. If the recording button 12 is pressed within the remaining recording time, the recording timer 132 is reset. Since the recording time can be extended, recording is possible only when necessary. For example, recording leakage can be prevented. In addition, since unnecessary recording is not performed, it is possible to record a sufficient amount of incidental scenes. Moreover, since the power of the built-in battery is not wasted, the built-in battery can be used for a long time. In particular, in this embodiment, since it is assumed that a police officer uses the wearable camera 1, shooting is not performed from the police station to the incident site, but can be performed after arrival at the incident site. it can.

  Note that the recording timer 132 is reset by performing W-LAN communication with a mobile terminal (not shown) such as a smartphone and performing a third party other than the user who is taking an image with the wearable camera 1 (for example, in the police car 520). Other police officers on board) may be reset by remote control on the portable terminal. Further, in a state where a link is established with the video recorder 21 of the in-vehicle camera system 2, it may be reset by remotely operating the PC 3 via the video recorder 21. In this case as well, a third party (for example, another police officer in the police car 520) is remotely controlled.

  The present invention has an effect of recording only when necessary, and can be applied to a camera that can be connected to an in-vehicle camera system such as a wearable camera.
